This is my first scope with a 7" screen and is much easier on old eyes than my 4" screen. The power button on the cord and the microscope appear to work. Whether against each other or together, I'm not sure. But when I turn off the oscilloscope with the power button on the screen, the oscilloscope turns off but the light stays on(?). Then you need to turn off the light with the switch on the cord. You can disable all work with a cable. Just a little eccentric at work. However, it is not difficult to understand. The only thing to note is that some assembly is required! This is the largest montage I've ever had to do with a microscope. I like it, just wish the service was a bit more sophisticated. But it's very useful and I love it.
